Recent results obtained by the KLOE experiment operating at DAPhiNE, the Frascati phi-factory, are presented. From a sample of about 10(9) phi-mesons produced at DAPhiNE, we select K-L and K-S tagged mesons. We present the preliminary results on the search for K-S --> 3pi(0), the branching ratio of the decay K-S --> pienu, and on the major K-L branching ratios, including the semileptonic decays relevant for the \V-us\ determination. A preliminary measurement of the K-L lifetime, using K-L --> pi(0)pi(0)pi(0) decays, is also given.

Abstract

Recent results obtained by the KLOE experiment operating at DAPhiNE, the Frascati phi-factory, are presented. From a sample of about 10(9) phi-mesons produced at DAPhiNE, we select K-L and K-S tagged mesons. We present the preliminary results on the search for K-S --> 3pi(0), the branching ratio of the decay K-S --> pienu, and on the major K-L branching ratios, including the semileptonic decays relevant for the \V-us\ determination. A preliminary measurement of the K-L lifetime, using K-L --> pi(0)pi(0)pi(0) decays, is also given.
